About
Test your reaction time in three rounds. Can your combined total beat one second?
1 Second Game brings the tension of a racing start to a quick reflex challenge. Hold the fingerprint pad as five lights come on. When they go out, release, find the target and tap. The wait changes and the target appears in a random position. Go too early and it's a false start.
EVERY TAP COUNTS
• See each round's time and your three-round total.
• Chase personal bests and daily, weekly and all-time Game Center leaderboards.
• Unlock achievements and share a personal-best image with friends.
• Choose from 20 languages, with optional music and haptic feedback.
• Play rounds offline. Game Center leaderboards require sign-in and an internet connection.
• Optional in-app purchases let you remove ads or support the developers through the Pit Crew.
Hold steady. Lights out. Go.
